Superior Parallel Imaging MS/MS Analyzer Performance

Integrated tandem mass spectrometers, i.e., Parallel Imaging MS/MS, for lossless collection of TOF-SIMS (MS1) and tandem MS (MS2) data, and with keV-CID for unambiguous peak identification and structural analysis.

Superior depth-of-field and uniform imaging sensitivity on curved or rough surfaces due to the large angular acceptance and band-pass kinetic energy window of the spectrometer.

Low spectral background and highest abundance sensitivity due to the automatic filtering of metastable post-source decay (PSD) ions.

High mass sensitivity for geological, organic and bio-medical applications.

Truly turn-key insulator analysis enabled by the newly patented pulsed dual-beam charge compensation technology.

Parallel Imaging MS/MS

TOF-SIMS is a fast MS imaging tool with consequently low mass accuracy and mass resolution that is an impediment to unambiguous peak identification.  PHI’s revolutionary and patented Parallel Imaging MS/MS spectrometer technology obliterates this limitation with an integrated and lossless time-of-flight (TOF) tandem MS (MS2) capability that makes use of high-energy (1.5 keV) collision-induced dissociation (keV-CID).  With the tandem MS enabled, a selected precursor ion (monoisotopic selection window) is deflected into the CID cell while the remaining ions continue to the TOF-SIMS (MS1) detector as usual.  The precursor ions collide with argon gas in the CID cell causing fragmentation, and the resulting product ions travel to the tandem MS (MS2) detector giving rise to the MS/MS (MS2) product ion spectrum.  Similar to the MS1 data, a full MS2 spectrum is collected for each image pixel.  Thus, TOF-SIMS and tandem MS data are collected simultaneously, in parallel, and without discarding any ions, from the same analytical volume.  All typical TOF-SIMS attributes remain, including high-speed imaging, high sensitivity, and high spatial resolution.

The MS2 product ion spectrum can be used to identify the precursor ion composition directly from the product ion spectrum or by comparison to mass spectral databases.  The Parallel Imaging MS/MS spectrometer also improves detection sensitivity for species in which the peak of interest has a mass interference by detection of a unique product ions.

MS/MS spectrum (MS2) obtained from CID fragmentation of the +m/z 481 precursor ion.  Identification of the fragment ions indicates that the precursor ion [M+H]+ is Tinuvin 770, a polymer additive.  

Further confirmation of the identity of the precursor ion is made with a positive match to Tinuvin 770 in a commercially available MS/MS database which is included with tandem MS/MS.  The spectrum in red is the MS2 spectrum and the blue spectrum is the acquired reference database spectrum of Tinuvin.

HR²

High spatial resolution with high mass resolution

HR² imaging is demonstrated below in the images of micro-organic droplets. In a single analysis, peaks for multiple molecular fragments were observed in the spectrum at m/z 57 with high mass resolution and identified by measurement of their exact mass. The distribution of each species was visualized with a spatial resolution of less than 400 nm. The single measurement that contains all this information was acquired in only six minutes due to the high ion beam current available in the PHI nanoTOF’s HR² imaging mode.

Cluster Source Ion Guns

FIB-TOF 3D Chemical Imaging

  • TOF-SIMS chemical imaging of in situ FIB-sectioned specimens. This can be performed using the liquid metal ion beam (LMIG) of the base system; however, 3D tomography requires the dedicated Ga-FIB option.
  • High mass resolution spectra are collected at every image pixel with uniform sensitivity is enabled by the Parallel Imaging MS/MS spectrometer. Delayed extraction is not used, so the artifacts of delayed extraction are completely avoided.
  • User-friendly 3D imaging software with multi-element overlay capability is provided.
